SDC LR100AWK Electric Latch Retraction Kit | For Arrow S1150 & S1250 Exit Devices

The SDC LR100AWK is a high-performance Electric Latch Retraction (ELR) kit specifically engineered to motorize existing Arrow mechanical exit devices. This field-installable retrofit kit is the premier solution for commercial door security, allowing seamless integration with modern access control systems without the high cost of replacing architectural panic hardware. By converting your manual bar into a motorized system, the LR100AWK serves as a cost-effective solution for door restoration in high-traffic schools, hospitals, and commercial facilities.

Motorized Access Control for Arrow Hardware

The SDC LR100AWK utilizes a quiet, high-torque motor to retract the latch and depress the pushpad simultaneously. It acts as a proactive solution for door surface repair by reducing the physical impact and mechanical wear associated with manual dogging:

• Arrow Device Compatibility: Precision-engineered specifically for the Arrow S1250 Rim Mounted and S1150 Surface Vertical Rod series exit devices.
  
• Simultaneous Latch & Pushpad Retraction: Unlike some competitive kits, the LR100AWK pulls the pushpad into the dogged (depressed) position while retracting the latch. This results in much quieter "push-pull" operation, making it an ideal solution for door restoration in noise-sensitive environments like libraries or healthcare wards.
  
• Sustained Electric Dogging: Perfect for high-traffic daytime use, the motor can hold the door in a dogged position via an access control schedule, while always maintaining code-compliant uninhibited egress for life safety.
  
• Intelligent Re-Trigger Technology: The onboard logic includes an automatic re-trigger function; if the device does not successfully pull on the first try, the motor automatically attempts a second retraction to ensure the door is unlocked.
  

Energy-Efficient Performance and Installation Benefits

Upgrading your facility to electronic locks doesn't have to involve a massive infrastructure overhaul. The SDC LR100AWK provides a streamlined solution for commercial door security with optimized power requirements:

• Low Current Draw: Features a remarkably low 700 mA inrush and a quiet 200 mA continuous hold at 24VDC. This efficiency eliminates the need for expensive, high-inrush power supplies—a single 1 Amp power supply can often handle up to two exit devices.
  
• Extended Wire Runs: The low current requirement allows for longer wire runs using smaller gauge wire, significantly reducing material costs during your solution for door restoration project.
• Fire-Rated Safety Compliance: This kit is UL Classified for use with 3-hour fire-rated and non-fire-rated exit devices, ensuring your building remains fully compliant with life safety regulations.
• Stable Mounting: Designed to integrate with the existing structural components of the Arrow device, ensuring the motor remains rigid and secure, similar to a high-strength thru bolt installation.
